The Sony Walkman, best known for playing some of the sweetest mix-tapes ever recorded entirely off the radio, will no longer be manufactured as of this year. Weird, I could have sworn this happened before Y2K.

The final batch was shipped to Japanese retailers in April, according to IT Media. Once these units are sold, new cassette Walkmans will no longer be available through the manufacturer.

The first generation Walkman (which was called the Soundabout in the U.S., and the Stowaway in the UK) was released on July 1, 1979 in Japan.

Somewhat ironically, the announcement was delivered just one day ahead of the iPod's ninth anniversary on October 23, although the decline of the cassette Walkman is attributed primarily to the explosive popularity of CD players in the '90s, not the iPod.

Fun fact: it wasn't actually the CD player that killed the cassette. You know what it was? Terrible music. Now I don't want to point any fingers, but I will sort of helicopter my penis in the direction of every 90's band that wasn't Nirvana. Whoa -- you catch a whiff of that? Smells like peen spirit.
